11 Claims.

This invention relates to an improved snap fastener member for securing a window strip molding or other suitable structure to a support.

An object of my invention is the provision of a snap fastener member of simple and inexpensive construction formed in a way to have improved fastener engagement with a supporting' part through an aperture thereof.

Other objects and uses of my invention will be apparent from inspection of the drawing and specification hereinbelow set forth.

Referring to the drawing, in which I have i1- lustrated preferred embodiments of my invention:

Fig. 1 is a top view of an installation showing a portion of a window channel support and a window guide strip secured to the support by means of my first form of fastener member;

Fig. 2 is a section taken along the line 2-2 of Fig. 1;

Fig. 6 is a front view of my improved fastener member per se;

Fig. 7 is a section taken along the line I--l of Fig. 2;

Fig. 8 is a sectional View showing a molding strip secured to a support by means of a modified form of my improved fastener member; and

Fig. 9 is a section taken along theline 9-9 of Fig. 8.

Referring to Figs. l and 2, which illustrate the preferred use of my rst form of fastener member, I have shown a fragment of a Window channel frame in the form of a supporting structure I providing an inner face 2 which bounds one side of the channel through which a window pane (not shown) is moved during the raising and lowering of the same. A exible strip 3 is attached to the support I in position so as to seal in an effective manner the face 2 of the support and the Window pane, as will be understood by those skilled in the art. The strip Whichl have chosen to employ in my preferred installation is of substantially elongated cross-section having a metal stifening core 4 and an outer covering ta of sturdy material. A nap means 5 is provided along one edge of the strip on the side facing away from the face 2 of the support I. A portion 6 of the strip adjacent the opposite edge thereof from that along which the nap 5 is disposed (Fig. 2) is adapted to 'be gripped by a hooklike element of my fastener member so as to secure the strip to the support I, as will be hereinafter described. The strip is attached to the support I by means of my improved fastener 5 members, each of which has a shank portion of improved construction extending through a circular aperture 'I in the support and firmly engaging' the material of the frame surrounding the aperture, as most clearly shown in Fig. 2. v

Referring in detail to my first form of fastener member per se, I have illustrated in Figs. 1-7 a snap fastener stud member made of one piece of sheet metal comprising a resilient shank portion for securing the fastener to a support and a hooklike means for engagement with the channel strip so Vas to clamp firmly'the strip to the support. In the preferred form my fastener member comprises a pair of side portions 8 and 9 connected at their leading ends I0. Portions of the side prtions 8 and 9 adjacent the leading ends I0 are disposed with opposed broad surfaces in pressed adjacent relation forming a nose II. The side portions 8 and 9 have portions I2I2 diverging from the nose I I and converging portions I3I3 forming shoulders. The side portion 8 has an attaching means in the form of a laterally extending portion 9a at its end away from the nose II for engaging the surface 2 of the support I. The side portion 9 has a laterally extending portion I5 integral with an end of the converging portion I3 (Figs. 2 and 4) for engagement with the surface 2 of the support I and a hook-like element I6 forming a continuation of the laterally extending portion I for engagement with the portion 6 of the channel strip 4. The hook-like element I6 preferably has teeth I I at its outermost free edge for biting engagement with the channel strip. It will be noticed that the converging portion I3 of the side portion 9, in my preferred form, is of less width than the diverging portion I2 whereby its relative narrowness enables the shoulder of the side portion to engage behind the support to a greater depth, as will be understood by those skilled in the art. The side portion 8 has a slit I8 extending from the outermost end of the laterally extending portion 98 through theshoulder a predetermined distance toward the nose I I thereby dividing a portion of the side portion into a pair of narrow leg portions L-Ila (Fig. 6), each 50 of which has a shoulder and a laterally extending portion I9. In order' that the legs 81--8L may effect a firm engagement with material of the support I surrounding the aperture 1, I have preferred to twist them outwardly at substan- 55 tially their junction with the side portion.

As a result of this construction, the legs have spaced inner edges with the planes of the broad surfaces of portions of the legs extending in angular relation, as most clearly shown in Fig. 7.` Thus, by being twisted, the legs 88-81 form separate relatively small arcs with the wall of the aperture 1, as most clearly shown in Fig. 7, so that their respective shoulders are securely engaged behind the support adjacent the aperture, as will be understood by those skilled in the art. Furthermore, my improved fastener is more flexible and more adaptable to certain uses than fasteners of sheet metal formed with two relatively wide legs.

Assembly of the component parts of the installation, with which I have chosen to illustrate the use of my first form of fastener member, is a relatively simple matter and is carried out through inserting the shank of the fastener member through the aperture 1 of the support whereby the shoulders of the narrow legs 8*-8 and the shoulder of the side portion 9 engage behind the support and cooperate to secure the fastener member securely to the support. The movement of the fastener member through the aperture in the direction of its insertion is limited by the laterally extending portions I9--I9 of the narrow legs 88---8a and the laterally extending portion I5 of the side portion 9. Finally, the strip 41s moved beneath the hook-like element I6 whereby the teeth I'I of the hook-like element bite into the material of the channel strip so as to hold it firmly in position. K

My second form of fastener member, illustrated in Figs. 8 and 9, is similar to my first form but includes certain modifications enabling it to be used for securing a molding strip or the like part to a support. Referring to the installation with which I have chosen to illustrate my second form of fastener, I have shown a support 20 having a circular aperture 2l and a molding strip 22 secured to the support 20 through means of my second form of fastener. The molding strip 22 is preferably of the type having opposed open ends and a side wall 23 adapted to be supported by the supporting structure and having an elongated aperture 23u running the entire length thereof (Fig. 8).

Referring to my second form of fastener member per se, I have shown a fastener having a pair of side portions 24-24 connected at their leading ends 25. The side portions are preferably pressed together adjacent their leading ends 25 forming a nose 26 which is similar in form to the nose I I ofmy first form of fastener member. The side portions diverge from the nose 26 and then converge forming shoulders 25u and the ends of the side portions away from their leading ends have outwardlyextending portions 26e for engagement with the inner surface of the side wall 23 of the molding. Each of the side walls 24-24 has a slot 21 extending from the outermost end of the respective laterally extending portion 2G into the diverging portion of the side portion dividing a portion of each of the side portions 24 into a pair of narrow leg portions 28-28 in the same manner in which the side portion 8 of my first form of fastener is divided by the slot I8 into the legs SL88. Each of the legs 28-28 has a shoulder 29 adapted to engage behind the support 20 and a laterally extending portion 30 bearing upon the inner surface of the wall 23 of the molding. lThe legs 28--28 of each of the pairs are preferably twisted outwardly near their junction with the respective side portion 24 so that the broad planes of portions of the legs of each of the respective pairs extend in angular relation, as most clearly shown in Fig. 9.l Y

In assembling my second form of fastener member with the molding, the laterally extending portions 30 are extended into one of the open ends of the molding and moved longitudinally of the molding to a predetermined position opposite one of the apertures of the support 20. Next, the shank of the fastener which extends through the elongated opening 23a of the molding is snapped through the aperture 2| of the support to dispose the shoulders 29.0f the four legs 28 behind the support, as shown in Fig. 8. Thus the four shoulders 29 of the legs cooperate with the laterally extending portions 30 to draw the molding firmly against the support.

Thus by my invention I have provided a fastener of simple construction having a support-engaging shank portion formed in a way to insure firm engagement with the support. n
